A high-definition camera or laser scanner 3 can be installed under the drone to monitor the surrounding situation and measure distances.

[0029] In this embodiment, the bomb carrier 4 in the bomb delivery system is fixed just below the center of gravity of the UAV body 1, and the shape of the bomb carrier 4 is selected according to the size of the UAV body and the shells.

The wheel-rail 13 is laid under the shell carrier 4. A single track or multiple tracks can be selected according to the number and size of the shells 9.

[0031] In this embodiment, the electromagnetic release control device is used to control the opening and closing of the hook. When the hook moves forward, the probe 5 on the boom touches the front receiver 6, and the hook opens. When the rear probe 5 collides with the front boom, the rear boom must reach a certain position to trigger the command to open the hook.

[0032] In this embodiment, the penetration head 8 in the belt-type artillery shell device is a pointed or round streamlined shape, and the material is generally high-strength steel or heavy metal alloy.

[0040] S60, performing detonation operation.

[0041] Example 1

[0042] As we enter a severe ice period, the sea ice range in the Bohai Sea and the Yellow Sea north of Dalian continues to expand. The maximum sea ice thickness in Dalian Port has reached 40 cm, and the area has reached 100 square kilometers. The entire offshore waters are covered with sea ice, which is a medium-risk ice dam. Drone bombs are used to break the ice.

[0043] The specific implementation steps are as follows:

[0044] Step 1: Design the blasting according to the ice terrain and under-ice flow rate of Dalian Port. Select a medium-sized drone with 8 explosives at a time. The single-section shell carries 6kg of explosives with a 5m interval. Use detonating cord to connect them. Select a 50m military explosion-proof hose.

[0045] Step 2, the assembled and connected shells 11 are loaded into the military explosion-proof hose 13 and fixed with the self-locking buckle 12.

[0046] Step 3, using a single wheel rail powered ejection device, the belt hanging ring 14 is directly hung on the powered propulsion hook 5.

[0047] Step 4: The UAV navigates to the designated launch location and controls the powered catapult according to the required initial launch velocity.

[0048] Step 5: After the drone completes the bombing operation, it automatically navigates to a safe area.

[0049] Example 2

[0050] A large area of ​​ice on the Songhua River has begun to melt, but there is still a 20cm layer of ice covering it, affecting the normal salvage operations of fishermen. It is necessary to carry out large-scale icebreaking operations on the river surface, using multiple large bomb-carrying drones to drop bombs and break the ice at the same time. Taking into account the large icebreaking area and the high cost of metal shells, belt shells are selected for icebreaking operations.

[0051] The specific implementation steps are as follows:

[0052] Step 1: Since the icebreaking area is large, a large-capacity drone equipped with belt-type shells is selected for icebreaking. According to the 16 shells carried at a time, the single-section shell carries 4kg of explosives and the interval is 4.5m, an 80m military explosion-proof hose is selected.

[0053] Step 2: Load the assembled and connected shells into the military explosion-proof hose and secure them with self-locking buckles.

[0054] Step 3: Use a dual wheel-rail ejection system to hang the hook in an S shape on the powered propulsion hook of the powered ejection device.

[0055] Step 4: The UAV navigates to the designated launch location and controls the powered catapult according to the required initial launch velocity.

[0056] Step 5: After the drone completes the bombing operation, it automatically navigates to a safe area.

[0057] Step 6, perform detonation operation.

[0058] Example 3

[0059] An ice dam appeared in the middle section of a river, blocking the river. The sharp increase in water level will further evolve into a breach. It is now necessary to blast the blocked ice dam. Considering that there are residents living on the river bank, in order to reduce the damage caused by the blasting shock wave, a drone equipped with small-amount explosives and multiple shells is selected to break the ice.

[0060] The specific implementation steps are as follows:

[0061] Step 1. Select a drone with a load of 50kg based on the surrounding environment and terrain, drop 10 shells at a time, select shells with a single charge of 4kg, with a spacing of 4m, and select a 50m military explosion-proof hose.

[0062] Step 2: Load the assembled and connected shells into a military explosion-proof hose and secure them with self-locking buckles or hemp ropes.

[0063] Step 3: Use a monorail powered catapult to hang the hook directly on the powered hook.

[0064] Step 4: The UAV navigates to the designated launch location and controls the powered catapult according to the required initial launch velocity.

[0065] Step 5: After the drone completes the bombing operation, it automatically navigates to a safe area.

[0066] Step 6: Use the detonating cord detonator to connect and perform the detonation operation.

[0067] Example 4

[0068] A 50cm thick ice layer appeared in the sea area of ​​nearly 100 meters near a port. The operation efficiency of icebreakers is slow and the cost is high. UAV bombing is used to break the ice. As there are hundreds of ships docked around the port, the fragments and shock waves of the explosion of metal shells will directly damage the hull and cause economic losses. Now UAVs equipped with belt bombs are used to break the ice, which can reduce the secondary disasters of the explosion under the premise of efficient ice breaking.

[0069] The specific implementation steps are as follows:

[0070] Step 1: Select a large drone with a load capacity of 100kg to 150kg, carry 20 shells at a time, and conduct long-distance and large-scale ice breaking. Connect them with detonating cords. A single shell carries 6kg of explosives, with a spacing of 6m. Select a 130m military explosion-proof hose.

[0071] Step 2: Load the assembled and connected shells into a military explosion-proof hose and secure them with a self-locking buckle or nylon rope.

[0072] Step 3: Hang the belt with a hanging ring directly on the power propulsion hook of the multi-wheel-rail powered catapult device.

[0073] Step 4: The UAV navigates to the designated launch location and controls the powered catapult according to the required initial launch velocity.

[0074] Step 5: After the drone completes the bombing operation, it automatically navigates to a safe area.

[0075] Step 6, perform detonation operation.
